 This script performs a network scan on a given target or subnet.
 It checks if the target hosts are alive, and if ports 80 (HTTP) and 443 (HTTPS) are open, and optionally performs reverse DNS lookups if specified.

 v1.1 2/2024 silversword411
 v1.4 added open port checker
 v1.5 5/2/2024 integrated reverse DNS lookup into the ping function with 1-second timeout
+v1.6 5/31/2024 align output to columns and ports low to high
+v1.7 2/18/2025 fix columns with long host names and added response time
 
-TODO: Make subnet get automatically detected instead of assuming /24
-TODO: Compatible with Linux as well
